BALINGr-PRESS.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 10, 1910. Serial No. 560,494.

To all whom it may concern:

Be it known that I, EDWARD J. STEINBER- GER, a citizen of the UnitedStates, residing at Defiance, in the county of Defiance and State ofOhio, have invented a new and useful 'Baling-Press, of which thefollowing is a specification.

This invention relates to baling presses and more particularly to meansfor controlling the end door of the press. In some forms of devices ofthis character an end door is employed and a plunger is utilized forcompressing hay or the like against the door to form a bale. The bale isthen tied. Another quantity of hay or the like is then supplied to themachine in the path of the plunger and it has been necessary to unlockthe door and raise it so that when this additional amount is compressed,the completed bale will be forced out of the press. In order that thedoor may be held 4 open until the completed bale has been discharged, ithas heretofore been customary to hold the door in its elevated positionby means of a stick which is struck by the eX- pelled bale and knockedfrom under the door, thus permitting the door to swing to its closedposition after which it can be locked. This arrangement has been foundobjectionable because it has required the attendance of at least twopersons for the purpose of raising the door and holding it while theprop is being placed under it. Moreover the prop is often knocked aconsiderable distance away from the press and considerable time is lostwhile one of the attendants is recovering it.

One of the objects of the present invention is to provide an end door orgate for a press which can be handled by one person, the said door beingprovided with a novel form of lock which can be readily released andmeans employed whereby the door when thrown open, will be automaticallyengaged and held and subsequently released by the bale disch'argedfromthe press.

With these and other objects in view the invention .consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings.:-Figure 1 is a perspective view of the discharge endof a baling press having the present improvements applied thereto. Fig.2 is a side elevation of the parts shown in Fig. 1 the door being shownsupported in its elevated position and the bale being shown, by dottedlines, moving against the'releasing member.

Referring to the figures by characters of reference, 1 designates thedischarge end portion of a baling press, and an end door 2 is hingedlyconnected to the top thereof as shown at 3, this door being adapted tofit between the side walls of the press when closed and being providedalong its lower free edge with a reinforcing cleat 4 on which isarranged a base plate 5. The cleat 4 is cut away or recessed under thelower or outer edge portion of the face plate 5 and adjacent the"centerthereof, as indicated at 6 for the purpose hereinafter set forth.Cross strips 7 are secured to the cleat 4 and extend across the faceplate 5, these cross strips constituting means for securing a trippingmember to the cleat. Said tripping member consists of an intermediaterod 8 having a central tongue 9 extending at right angles therefrom andside arms 10 which extend across the cleats 4 and merge into asubstantially V-shaped hanger 11. This hanger -extends at right anglesor substantially at right angles to the arms 10.

Hangers 12 are secured to the sides of the press 1 and are connected bya cross rod 13 on which is mounted a locking element consisting of aV-shaped retaining member 14 having U-shaped extensions 15 extending atright angles from the terminals thereof and pivotally mounted on therods 13. A keeper, in the form of an elongated bail 16, is pivotallymounted on the top ofthe press -1 and is adapted to embrace and hold theapex portion of the retaining member 14 so as to bind said membertightly against the cleats 1 when the door is closed. This bail 16preferably has a tongue 17 extending from its free end and whereby itcan be readily manipulated.

A standard 18 is secured upon the top of the press 1 and a brace19.extends downwardly therefrom and is secured atone end to the top ofthe press 1. The other end of the brace extends beyond the open end ofthe press and is inclined downwardly as indicatedjat 20, this projectingportion being forked as shown at 21. A latch strip 22 is pivotallymounted within the fork 21 and has a downwardly curved head 23 at onedid while its other end is formed with laterally extending stop ears 24adapted to bear up wardly against the fork 21 and thus limit thedownward movement of the head 23.

In using the device, the door 2 is locked by swinging the member 14:against the cleat and then dropping the bail 16 into-engagement with theupper or, apex portion of said member 14. It will be seen thereforethat, when the plunger, not shown, is reciprocated, the hay or othermaterial in the path thereof will be compressed against the door and abale thus formed which can be tied and thus completed. Uponthecompletion of the bale the bail 16 is lifted by means of'the tongue17 so as to release the retaining member 14 and this member will thusdrop downward by gravity and assume a position be.- neath the press, asindicated in Fig. 2.

' When another quantity of material to be baled is then placed withinthe press, the plunger, upon its next forward or compressing stroke,will force this additional material against the completed bale and thusdrive said bale against the unlocked'door. The said door will thereforebe swung upwardly and the base plate 5 will strike the head 23 and saidhead will drop into engagement with that portion of the base plateoverhanging the recess 6. The door. will therefore be kept open untilthe bale has been pushed a sufficient distance out of the press to causeit to tilt downwardly and drop therefrom. As the bale tilts and falls,the upper end thereof kicks against the hanger 11 and causes the rod 8to partly rotate. Tongue 9., which .rests directly under the latch 22,will thus be elevated and lift the head 28 out of engagement with theplate 5. The door 2 will therefore drop by gravity to its closedposition and the operator can swing the retaining member l'upwardly andplace the bail 16 in engagement therewith. The foregoing operations canthen be repeated. I V

Various changes can of course be made in the construction andarrangement' f the parts without departing from the spirit orsacrificing any of the advantages of the invention as defined in theappended claims.

What is claimed is v 1. A baling press having an end door, said doorbeing shiftable to open position 7 by an expelled bale, means forautomatically locking the door in open position, and means operated bythe expelled bale for releasing the door.
